先构建一份ui:

自动生成文件1：moc_gotocelldialog.cpp

1、手动完成UI的建立，然后在cmd 中用qmake -project 命令，生成gotocell.rpo（父目录即为工程名），再用make gotocell.pro中生成工程。需要在VS中编辑文件时：再使用qmake -tp vc gotocell.pro即可。上面的两份代码均为自动生成的

2、gotocelldialog.h

#ifndef GOTOCELLDIALOG_H

#define GOTOCELLDIALOG_H

#include

#include "ui_gotocelldialog.h"

class GoToCellDialog:public QDialog,public Ui::GoToCellDialog

{

Q_OBJECT

public:

GoToCellDialog(QWidget *parent = 0);

private slots:

void on_lineEdit_textChanged();

};

#endif

3、gotocelldialog.cpp

#include

#include "gotocelldialog.h"

GoToCellDialog::GoToCellDialog(QWidget *parent)

:QDialog(parent)

{

setupUi(this);

QRegExp regExp("[A-Za-z][1-9][0-9]{0,2}");

lineEdit->setValidator(new QRegExpValidator(regExp,this));

connect(okButton,SIGNAL(clicked()),this,SLOT(accept()));

connect(cancelButton,SIGNAL(clicked()),this,SLOT(reject()));

}

void GoToCellDialog::on_lineEdit_textChanged()

{

okButton->setEnabled(lineEdit->hasAcceptableInput());

}

3、main函数：

#include

#include

#include "gotocelldialog.h"

int main(int argc,char *argv[])

{

QApplication app(argc,argv);

GoToCellDialog *dialog = new GoToCellDialog;

dialog->show();

return app.exec();

}

如果是用vs编辑工程的话，每次加入消息传递就是信号槽等处理，都得重新用cmd重新生成工程
